57STH56M30X01 is a 57 mm hybrid stepper motor with a 0.9° step angle and 1 Nm holding torque. It has a rated current of 3.00 A per phase (2-phase ON), coil resistance of 0.65 Ω, and inductance of 3.4 mH. The motor features ball bearings, a rotor inertia of 280 g·cm², and operates within an ambient temperature range of -20 to +50 °C with a maximum coil temperature of 130 °C (Class B). It supports 400 steps per revolution, has a maximum radial force rating of 75 N at 20 mm from the flange, and an axial force limit of 15 N. The motor uses AWG22 UL1007 leadwires, weighs 700 g, and meets a dielectric withstand voltage of 500 VDC. All data are specified at 20 °C.
57STH56 High Precision Hybrid Stepper Motor
57STH56M
The 57STH56-High Precision is a 2 phases 0.9° hybrid stepper motor. This high resolution stepper motor has half the step angle of standard stepper motors. The high precision type increases motor resolution from 200 steps/revolution to 400 steps/revolution. Smaller step angles can be achieved by half-step driving or microstep driving. If the pulse speed is within resonance region, vibration may increase. The stopping accuracy improves as the torque increases while minimizing the negative effect of the frictional load. Resonance regions can be avoided by switching to a 0.9° high-resolution type stepper motor.
